A Taxonomy of Extended Radio Sources in Clusters of Galaxies
Joshua C. Kempner, Elizabeth L. Blanton, Tracy E. Clarke +3
At the request of the conference attendees, we have compiled a classification of extended radio sources in clusters. These range from scales of tens of parsecs to over a megaparsec…
On the Radiation Damage of BTeV EMCAL Detector Unit
A. Borisevich, V. Dormenev, G. Drobychev +7
Hamamatsu photomultiplier tubes (PMT) and various PMT window materials were exposed to gamma irradiation. Tests were performed with absorbed doses of 1 krad and 120 krad. Initial r…
Three-Dimensional Simulations of the Parker Instability in a Uniformly-rotating Disk
Jongsoo Kim, Dongsu Ryu, T. W. Jones
We investigate the nonlinear effects of uniform rotation on the Parker instability in an exponentially-stratified disk through high-resolution simulations. During the linear stage,…
Cosmic Rays and Their Radiative Processes in Numerical Cosmology
Dongsu Ryu, Francesco Miniati, Tom W. Jones +1
A cosmological hydrodynamic code is described, which includes a routine to compute cosmic ray acceleration and transport in a simplified way. The routine was designed to follow exp…
Gapped Phases of Quantum Wires
O. A. Starykh, D. L. Maslov, W. Häusler +1
We investigate possible nontrivial phases of a two-subband quantum wire. It is found that inter- and intra-subband interactions may drive the electron system of the wire into a gap…
Large Cosmic Shock Waves as Sites for Particle Acceleration
Francesco Miniati, Dongsu Ryu, Hyesung Kang +1
The properties of cosmic shock waves are studied through numerical simulations in two cosmological scenarios (SCDM and LCDM). The scaling relations for the average radius and veloc…
